DISCUSSION
THROUGH FRIDAY...
THE SHORTWAVE AND ASSOCIATED COLD FRONT THAT DROPPED THROUGH THE
AREA LAST NIGHT AND THIS MORNING BROUGHT BENEFICIAL RAINFALL TO
PORTIONS OF THE AREA, ESPECIALLY TO THE SOUTHERN MOUNTAINS AND
FOOTHILLS. SOME LOCATIONS IN THE MOUNTAINS AND FOOTHILLS RECEIVED
NEAR OR MORE THAN AN INCH OF LIQUID PRECIPITATION (RAIN AND MELTED
SNOW), WITH LIGHT SNOW ACCUMULATIONS ABOVE 7,500 FT. CYCLONIC FLOW
REMAINS OVER THE AREA, AND ISOLATED SHOWERS CAN BE EXPECTED
THROUGH THE REST OF THE AFTERNOON, DECREASING INTO THE EVENING
HOURS. AS SKIES CLEAR OUT TONIGHT, TEMPERATURES WILL DROP INTO THE
30S AND 40S, LOWEST NEAR THE FOOTHILLS. FROST IS POSSIBLE
(MODERATE CHANCE) FOR FOOTHILL LOCATIONS TONIGHT INTO SUNDAY
MORNING. PROTECT SENSITIVE VEGETATION.
CONDITIONS TREND DRIER INTO TUESDAY, OUTSIDE OF OCCASIONAL PIECES
OF ENERGY BRINGING ISOLATED SHOWER AND WEAK THUNDERSTORM ACTIVITY
TO THE MOUNTAINS AND FAR EAST IN THE AFTERNOONS/EVENINGS. BY LATE
TUESDAY INTO WEDNESDAY, A STRONGER WAVE IS PROGGED TO DROP THROUGH
NORTHWEST FLOW BRINGING SHOWER/THUNDERSTORM CHANCES AND BREEZY
WINDS. THERE IS CURRENTLY A MODERATE CHANCE AT 40 MPH WIND GUSTS
FOR WESTERN FOOTHILL LOCATIONS TUESDAY. BEST PRECIPITATION
POTENTIAL IS CURRENTLY FOR AREAS NORTH AND EAST OF BILLINGS
(20-60% CHANCE). OCCASIONAL PIECES OF ENERGY WILL CONTINUE TO
MOVE THROUGH THE FLOW THROUGH THE END OF THE WORK WEEK, ALLOWING
ISOLATED AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS TO CONTINUE.
HEADING INTO THE WEEKEND, THERE ARE HINTS THAT UPPER TROUGHING
MOVES ONTO THE WEST COAST, INDUCING SOUTHWEST FLOW OVER THE
REGION, WITH A BETTER POTENTIAL FOR DAILY THUNDERSTORMS.
TEMPERATURES ARE FORECAST TO RANGE FROM THE 60S TO LOWER 70S
SUNDAY, TO THE 70S TO AROUND 80 DEGREES MONDAY. THE WARMEST DAY OF
THE WEEK CURRENTLY LOOKS TO BE TUESDAY WITH HIGHS IN THE 70S TO
MIDDLE 80S, BEFORE TEMPERATURES COOL BACK INTO THE 70S FOR MOST
AREAS THE REMAINDER OF THE WEEK. STP
AVIATION
ISOLATED LIGHT SHOWERS ARE EXPECTED ACROSS THE REGION TODAY
